The atomic mass of al is 26.98154 g/mol. is it possible to have 5.0 x 10^-25 g of al?

First let us calculate the number of moles.

number of moles = (5.0 x 10^-25 g) / (26.98154 g/mol)

number of moles = 1.853 x 10^-26 mol

We then calculate the number of atoms using Avogadros number.

number of atoms = (1.853 x 10^-26 mol) * (6.022 x 10^23 atoms / mole)

number of atoms = 0.011 atoms

There can never be an atom of less than 1 since 1 unit of atoms is the basic unit of all elements. Therefore it is NOT possible.

it is called acid bonding

i'm assuming that the correct answer is indeed the first one/ "a"..
